I love the library system in my area. Many of the books are in an ebook format, which makes my late-night reading binges easier to handle. The ease and convenience of ebooks is wonderful for me. I have an ipad mini and several (old, but working) laptop and computer devices at my disposal with the Kindle app. The sheer number of books on my device make me happy and traveling much easier.
Again, I love the library system in my area. The main branch is absolutely stunning and I have spent hours at a time looking through their vast catalog, and continue to do that once a week when I am in the city for uni. I always find at least one book (and DVDs) each time I go to a library and much of that is when I find a book that catches my eye, I pick a random spot and start reading to see if it holds my interest.
When adding to my personal book library, I will always buy a physical book and not an ebook. I simply like looking at books and ebooks do not give me that type of satisfaction since I don't feel like I 'own' them.
